+# Linux GRUB 引导修复工具 (BootRepairTool) 安装脚本
+# ------------------------------------------------------------------------------
+# 功能:
+#   1. 下载应用程序可执行文件、图标。
+#   2. 创建安装目录 `/opt/boot-repair-tool`。
+#   3. 创建软链接 `/bin/boot-repair`。
+#   4. 创建并安装桌面入口文件 (.desktop) 到 `/usr/share/applications`。
+#   5. 创建 PolicyKit 规则文件，确保 pkexec 正常工作。
+#   6. 更新桌面数据库，使应用程序显示在菜单中。
+#
+# 使用方法:
+#   1. 终端中运行: sudo bash install.sh
